Why do we need this? That's not rhetorical, I'd like to
hear of any use cases where you think a problem could arise.
To me the bigger problem with a module-based solution is the
complete separation of all string processing modules into
those that are utf8-aware, and those that aren't. A fork
which extends to other modules which use string-processing
modules, i.e. duplicate copies of most code.
